I think Carolyn R and Minimor are saying the same thing in their own ways....make sure the foal gets proper, regular trims and then consider if some corrective trimming is necessary. I've also learned that simply squaring the toe can help with break over point and straighten them naturally without lowering heal.
You are correct, that is why I put the last statement that "
Overmanipulating their hooves creates more issues".
Trust me, I am not new to horses, unless 25+ years with them is new, LOL. It is imperitive that the hoof is balanced,and yes, foals should have their feet trimmed often, just not overmanipulated, esp. for mild toeing in a very young foal. Minimor and Bevann, the poster was inquiring about toeing out in foals, as far as anything drastic, I would leave that to the professionals (but IMHO if it were drastic issues, I don't think it would be something I would consider for serious driving down the road)
ZOEY3 it is good that you are asking these questions now and not just going into things blindly. If you are unsure of the severity of the toeing, if it is an acceptable -minimal- amount or ones that would need corrective trims by a professional, ask a knowledgeable horseperson to accompany you (or pay a ferrier or vet to take a look). It is always tricky buying a young horse, you never know how things will pan out, the more knowledge you gain before the purchase the better.
Good Luck
